![]() Hence, we FLIP the original greater than sign (>) to a less than sign (<), which changes the entire format of the graph (or at least the solutions to the problem). In order to isolate the y variable we have to divide it by -5, along with other expression of the inequality (8x+1). ![]() For instance, if you have the linear inequality -5y>8x+1, you might initially assume that the solutions to the inequality will be represented by shading the half plane that is above the y-intercept 1, but this is incorrect. If it is a negative you are going to want to flip the direction of the sign. Then, look at the the y term-not y-intercept. If there is no line under the inequality sign, it is deemed non-inclusive, indicating a dashed line. The data points on a coordinate plane are written as an ordered pair and are written as (x, y). The point of intersection is called the origin. The vertical line is called the y-axis, and the horizontal line is called the x-axis. If it has a line directly below it, it is deemed inclusive, indicating a solid line. A coordinate plane is a system for plotting points that is represented by two axes that meet and form a right angle. So, here's my tip: when looking to find the graph of an inequality, look at inequality sign first. The shaded region for the inequality is above the line. There is a dashed line representing an inequality that goes through the points negative one, one point seven-five and zero, negative one point two-five. The coordinate plane is split into four quadrants. The intersection of these lines creates the origin, which is the point (0,0) ( 0, 0). The coordinate plane is comprised of a horizontal ( x -) axis and a vertical ( y-) axis. Hi! I know this is late and that you 100% won't see this comment, BUT I like to help and LOVE math. A coordinate plane with a graphed system of inequalities. The coordinate plane is a system for graphing and describing points and lines.
